What is Private Property?

Is the ideal of private property something that we should uphold?  If the answer is "yes", this video is fairly shocking in the violation of this ideal.  Obviously, there is always another side to every story, and we get 'a spin' that the producers wish for us to see, but given all that we are researching and investigating in the Bay Area, the other side of the story here may shock us even further rather than give us comfort that "all is well" here...
